Greyhound Forecast Bet: How It Works and What It Pays

Forecasts Turn a Result Into a Bigger Question

Picking the winner is one thing — picking the exact first and second is another level. A forecast bet in greyhound racing asks you to do precisely that: identify not just which dog crosses the line first, but which one follows it home. The reward for getting it right is significantly higher than a simple win bet, because the difficulty is significantly greater.

Forecast betting is one of the most popular markets in UK greyhound racing. It sits at the intersection of form analysis and calculated risk — you need to know enough about the runners to narrow the field, but you also need to accept that with six dogs in contention, the number of possible first-and-second combinations is larger than most casual bettors realise. Understanding how forecasts work, how dividends are calculated, and how to structure your approach is the difference between occasional lucky hits and a repeatable betting method.

Three variants of the forecast bet exist in greyhound racing: straight, reverse, and combination. Each changes the balance between risk, cost, and potential return. This guide covers all three, along with the factors that determine how much a forecast actually pays out when it lands.

Straight Forecast: First and Second in Order

A straight forecast pays when you call the exact 1-2 finish. You select two dogs and specify which one will win and which will come second. If they finish in the order you predicted, the bet wins. If they reverse positions — your first pick runs second and your second pick wins — the bet loses. There is no flexibility in the outcome. The precision is the point.

To place a straight forecast, you select your two runners in most bookmaker interfaces by adding them to the bet slip and choosing the “forecast” option. The first selection goes in the “1st” position, the second in the “2nd” position. Some bookmaker apps make this more intuitive than others. On the Tote and at the track, you simply state your forecast to the operator or enter it on the pool betting terminal.

The payout on a straight forecast is not a fixed-odds calculation. In most cases, greyhound forecast dividends are determined by the Computer Straight Forecast (CSF), which is a formula-based return calculated after the race. The CSF takes into account the starting prices of the first two finishers and produces a dividend per one-pound unit stake. This means you cannot know the exact return before the race — unlike a win bet where you take a price, the forecast dividend is only declared once the result is confirmed.

Some bookmakers do offer fixed-odds forecasts, where the price is quoted and locked in at the time of the bet. These tend to be less generous than CSF returns because the bookmaker is taking on the risk of the dividend being larger than expected. If you see a fixed-odds forecast price, compare it mentally against what a CSF might return. Over time, CSF dividends on greyhounds tend to produce better value for the punter, though they come with the uncertainty of not knowing the exact payout in advance.

The CSF formula weights the result by the SPs of the two dogs involved. When the winner is at a short price and the second dog is also well-fancied, the CSF dividend is modest — perhaps in the range of 5 to 15. When the winner is a bigger price, or the runner-up is unexpected, the dividend climbs sharply. A 5/1 winner followed by a 6/1 runner-up might produce a CSF dividend of 40 or more, depending on the full field and the distribution of prices across all six runners.

This is the appeal of straight forecasts in greyhound racing: a relatively small stake can produce a substantial return if both selections are outside the market leader. It is not unusual to see greyhound forecast dividends in the 50 to 200 range, and occasionally higher, when an outsider fills one of the first two spots.

Reverse Forecast: First and Second in Any Order

Two bets in one — either order wins. A reverse forecast is simply two straight forecasts combined. You select two dogs, and you are covered regardless of which one finishes first and which finishes second. If Dog A wins and Dog B runs second, you win. If Dog B wins and Dog A runs second, you also win. The cost is double that of a straight forecast, because you are placing two separate bets.

The logic behind a reverse forecast is straightforward: you have identified two dogs that you believe will fill the first two places, but you are not confident about the order. Perhaps both are front-runners drawn in adjacent traps, or perhaps one has strong early pace while the other tends to finish well. You rate them equally capable of taking the win. Rather than guess which way round the result will fall, you cover both permutations.

The dividend returned on a reverse forecast is the CSF for the actual finishing order, applied to your unit stake. If you place a one-pound reverse forecast, your total stake is two pounds (one pound on each permutation). Whichever permutation wins, the CSF is calculated as normal. You receive the dividend for the winning permutation only — the losing half of the reverse is simply lost.

This means the break-even threshold on a reverse forecast is higher than on a straight forecast. You need the winning CSF dividend to cover both the winning and losing stakes. In practice, most greyhound forecast dividends comfortably exceed the two-pound total stake on a one-pound reverse, so the market is not inherently stacked against this approach. But it is important to remember that the extra cost is real. A reverse forecast at five pounds per line costs you ten pounds. If the dividend comes back at eight, you have made a loss despite technically being right about the two dogs.

Reverse forecasts work best when you have strong conviction about two runners but genuine uncertainty about the finishing order. If you have a clear view that one dog should beat the other, a straight forecast is the more efficient bet. The reverse is a hedge, and like all hedges, it reduces risk at the cost of reducing return.

Combination Forecasts: Covering Multiple Dogs

More coverage, more stakes — the trade-off is always the same. A combination forecast allows you to select more than two dogs and cover all possible first-and-second permutations between them. If you pick three dogs, you get six straight forecast combinations. Pick four, and you have twelve. Five selections produce twenty permutations. Each permutation is a separate bet at your unit stake.

The maths is simple: for any number of selections, the number of forecast permutations equals the number of selections multiplied by one less than the number of selections. Three dogs: 3 x 2 = 6. Four dogs: 4 x 3 = 12. The total cost of your combination forecast is your unit stake multiplied by the number of permutations.

Combination forecasts are useful when you can identify a group of likely contenders but cannot separate them into a clear first and second. In a race where four dogs look competitive and two look outclassed, a four-dog combination forecast covers all twelve possible outcomes among your four picks. If any two of them fill the first two places, in any order, your bet wins.

The drawback is cost. A one-pound combination forecast on four dogs costs twelve pounds. To profit, the CSF dividend needs to exceed twelve — which is entirely possible if the two dogs that actually finish first and second are at reasonable prices, but not guaranteed. If the market favourite and second favourite fill the places, the CSF might come back at eight or ten, leaving you with a net loss despite selecting both dogs.

The skill in combination forecasting is in choosing the right number of selections. Three is the sweet spot for most bettors: six permutations at a manageable cost, with a high probability that at least one pair fills the places if your three selections are well-chosen. Going wider — four or five selections — increases your strike rate but dilutes the return. The wider you go, the more you are paying for insurance, and at some point the insurance costs more than the occasional payout justifies.

One useful discipline: before placing a combination forecast, calculate the minimum CSF you need to break even. If your total stake is eighteen pounds (three pounds per line on a six-line combination), the CSF needs to be at least eighteen for you to break even and higher for profit. Glance at recent CSF dividends for similar race types to get a sense of whether that threshold is realistic.

What Affects Forecast Dividend Size

Bigger prices in the top two mean bigger dividends. That is the single most important thing to understand about forecast returns. The CSF formula is driven primarily by the starting prices of the first and second finishers. When both dogs are short-priced, the dividend is compressed. When one or both are at longer odds, it expands.

Consider two scenarios from the same race. In the first, the 6/4 favourite wins and the 2/1 second favourite runs second. The CSF might return somewhere between 5 and 10. In the second scenario, the 5/1 shot wins and the 8/1 outsider finishes second. That same CSF formula could produce a dividend of 60, 80, or more. The difference is enormous, and it all comes from the underlying prices.

This has a practical implication for how you approach forecast betting. If you are forecasting two well-fancied dogs, the return will be modest relative to the risk. You might be right about the result, but the payout barely justifies the effort. If, on the other hand, you can identify a scenario where a less obvious runner finishes in the top two, the dividend rewards that insight handsomely.

Other factors that influence the CSF include the number of runners — though in UK greyhound racing this is almost always six — and the spread of prices across the field. A race where one dog is odds-on and the other five are at double-figure prices produces a different CSF landscape than a race where all six runners are priced between 2/1 and 6/1. Competitive, open races with no standout favourite tend to generate the most attractive forecast dividends, because the market is not concentrated on any single outcome.

Two From Six: The Odds You’re Really Facing

Thirty possible outcomes — you are backing one. In a six-runner greyhound race, there are exactly 30 possible first-and-second combinations. A straight forecast targets a single one of those 30. A reverse forecast targets two. Even a three-dog combination forecast covers only six.

Those numbers are worth holding in your head, not as a deterrent, but as a calibration tool. Forecast betting is not about certainty. It is about narrowing the field to a subset of likely outcomes and accepting that you will be wrong more often than you are right. The returns, when you are right, are designed to compensate for that frequency of loss — but only if you are disciplined about stake sizing and selective about which races merit a forecast bet at all.

Not every race is a forecast race. The ones that reward forecast thinking are the races where you have a genuine opinion about two or more dogs that differs from the market. When you can look at a six-dog field and say, with evidence, that a particular pair has been underestimated — that is when the forecast market starts working in your favour.
